Just tested (albeit briefly) the 3.0R-B (6-speed manual). Compared to the GT, it blew me away. I liked the GT, but I loved the Spec B - especially the sound. The GT has pretty-much lost the boxer burble and sounds like a generic 4 cylinder - the Spec B sounds like a cross betwen a BMW straight-6 and a Porsche/ Alfa GTA. I L-U-R-V-E it!!!
